[0047] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0048] like Figures 1 to 3 As shown, an embodiment of the present invention provides a bolter miner, which includes a body 10 and a walking structure 20. The walking structure 20 includes a walking frame group 21, multiple rolling parts 22 and a crawler 23. The multiple rolling parts 22 are all arranged at the outer periphery of the walking frame group 21, and the crawler 23 is mounted on the multiple rolling parts 22. Among them, the walking frame group 21 includes a fixed frame 211, a lifting frame 212 and a tensioning frame 213. The fixed frame 211 is fixedly connected to the body 10, and the lifting frame 212 is movably arranged below the fixed frame 211, and the fixed frame 211 is supported on the lifting frame 212; the tensioning frame 213 is movably arranged on the fixed frame 211 and located above the lifting frame 212, and the end of the tensioning frame 213 extends out of the end of the fixed frame 211. The fixed frame 211, the lifting frame 212 and the tensioning frame 213 are all provided with a rolling part 22; when the lifting frame 212 descends, the tensioning frame 213 moves toward the direction of the fixed frame 211; when the lifting frame 212 rises, the tensioning frame 213 moves away from the fixed frame 211.

[0049] When the anchor miner provided by the present invention is operating in a tunnel with elevated ground, the lifting frame 212 is controlled to descend relative to the fixed frame 211, causing the fixed frame 211 to rise relative to the lifting frame 212, thereby raising the chassis structure of the machine body 10. This prevents the chassis structure of the machine body 10 from being scratched by the elevated ground structure, effectively protecting the chassis, ensuring normal and stable operation of the anchor miner, and reducing the risk of chassis damage. Furthermore, through the coordination of the tensioning frame 213, the lifting frame 212 maintains tension on the crawler track 23 during the raising and lowering process, thereby ensuring normal operation of the traveling structure 20 and ensuring the stability of the anchor miner in the tunnel. Therefore, the anchor miner provided by the present invention solves the technical problem of the chassis being easily scratched when operating in a tunnel, as is commonly seen in the prior art.

[0050] Furthermore, this design enables the miner to automatically adjust the height of the lifting frame 212 based on ground undulations in complex working conditions such as coal mines and tunnels, ensuring the proper tension of the crawler tracks 23. This improves travel stability and reduces the risk of derailment, thereby minimizing operational interruptions and improving efficiency. This design is particularly well-suited for handling irregular terrain and complex conditions within coal mine tunnels, ensuring the machine's continued operational capabilities.

[0051] In this embodiment, the fixing frame 211 extends in a predetermined direction, with one end of the fixing frame 211 extending from one end of the lifting frame 212. The tensioning frame 213 is movably mounted on the fixing frame 211 in a predetermined direction, with one end of the tensioning frame 213 extending from the other end of the fixing frame 211. Both the other end of the fixing frame 211 and the end of the tensioning frame 213 are provided with rolling portions 22. This structural arrangement facilitates the tensioning of the crawler track 23 through the movement of the tensioning frame 213, and also facilitates the movement of the crawler track 23 through the rolling portions 22 at the other end of the fixing frame 211 and the end of the tensioning frame 213, thereby enabling the crawler track 23 to travel normally.

[0052] Specifically, the plurality of rolling parts 22 include a first drive wheel 221, and the anchor miner further includes a first drive member. Both the first drive wheel 221 and the first drive member are mounted on one end of the fixed frame 211. The first drive member is drivably connected to the first drive wheel 221 to drive the first drive wheel 221 to rotate. This structural arrangement, combined with the positioning of the first drive wheel 221, facilitates better movement of the crawler track 23 by driving the first drive wheel 221.

[0053] Specifically, the plurality of rolling parts 22 include a second drive wheel 222, and the anchor miner further includes a second drive member. Both the second drive member and the second drive wheel 222 are mounted at the end of the tensioning frame 213. The second drive member is drivingly connected to the second drive wheel 222 to drive the second drive wheel 222 to rotate. Thus, combined with the location of the second drive wheel 222, driving the second drive wheel 222 facilitates smoother movement of the crawler track 23.

[0054] Furthermore, the dual-drive wheel structure of the first drive wheel 221 and the second drive wheel 222 enables the bolter miner to achieve greater traction while traveling, improving its operating efficiency in complex terrain. This is particularly true during coal mine tunneling, where it can effectively navigate various obstacles and uneven surfaces. This dual-drive wheel design significantly enhances the miner's traction and control capabilities, enabling more stable and efficient tunneling operations in complex terrain, reducing its dependence on the coal mine tunnel environment and enhancing the machine's adaptability and flexibility.

[0055] In this embodiment, the fixed frame 211 is provided with a mounting slot 2111 extending in a predetermined direction. The tensioning frame 213 includes a connecting section 2131 and an extending section 2132, which are interconnected. The connecting section 2131 conforms to the shape of the mounting slot 2111. At least a portion of the connecting section 2131 is movably disposed within the mounting slot 2111 along a predetermined direction. The extending section 2132 extends beyond the mounting slot 2111 and forms the end of the tensioning frame 213. This structural arrangement not only facilitates the installation of the tensioning frame 213 and improves the installation stability of the tensioning frame 213, but also facilitates adjustment of the extension length of the extending section 2132, thereby ensuring that the tensioning frame 213 can tension the track 23.

[0056] This structural design not only simplifies the installation and maintenance of the track 23 tensioning system, but also ensures consistent track tension under varying operating conditions, improving the efficiency and safety of the anchor miner during coal mine excavation. During coal mine excavation, this tensioning system quickly responds to changing ground conditions, automatically adjusting the track 23 tension to ensure optimal operation under all conditions. This reduces track wear and the risk of derailment, improving machine reliability and efficiency.

[0057] In this embodiment, the bolter miner further includes a drive structure 30, which is mounted within the mounting slot 2111. The drive end of the drive structure 30 is telescopically arranged along a predetermined direction and is connected to the connecting section 2131 to drive the movement of the connecting section 2131. This facilitates installation of the drive structure 30, improves its installation stability, optimizes the structural layout, and enhances its overall compactness.

[0058] Furthermore, control of the drive mechanism 30 enables precise adjustment of the track tension 23, improving the bolter miner's travel accuracy during coal mine tunneling, reducing friction and damage to the tunnel walls, and extending the equipment's service life. The precise control of the drive mechanism 30 enables the bolter miner to operate in a variety of complex environments, such as the confined spaces and irregular terrain found in coal mine tunneling. By fine-tuning the track tension 23, excessive wear on the tunnel walls is reduced, protecting the tunnel structure, extending the equipment's service life, and reducing maintenance costs.

[0059] Specifically, the connecting section 2131 is provided with a guide groove 21311 extending in a predetermined direction. The mounting groove 2111 is provided with a guide protrusion 2112 adapted to fit within the guide groove 21311. The guide protrusion 2112 is disposed within the guide groove 21311. Thus, the coordination between the guide groove 21311 and the guide protrusion 2112 ensures the stability of the tensioning frame 213 during movement, making the movement of the tensioning frame 213 smoother and facilitating better tensioning of the track 23 through the movement of the tensioning frame 213.

[0060] Alternatively, the connecting section 2131 is provided with an avoidance opening groove and a guide groove 21311 that are interconnected, and the guide groove 21311 extends along a preset direction. The anchor miner also includes a guide protrusion 2112, which is movably provided on the fixed frame 211, and the guide protrusion 2112 has a guiding position and an avoidance position; when the guide protrusion 2112 is in the guiding position, the guide protrusion 2112 extends into the avoidance opening groove and cooperates with the guide groove 21311 for guidance; when the guide protrusion 2112 is in the avoidance position, the guide protrusion 2112 avoids the avoidance opening groove so that the connecting section 2131 is installed in the installation groove 2111. In this way, it is convenient to install the tensioning frame 213 when the guide protrusion 2112 is in the avoidance position; when the guide protrusion 2112 is in the guiding position, the stability of the tensioning frame 213 during movement can be ensured, making the movement of the tensioning frame 213 smoother, so that the track 23 can be better tightened through the movement of the tensioning frame 213.

[0061] In this embodiment, the plurality of rolling parts 22 include a first driving wheel 221 , a second driving wheel 222 and a plurality of guide wheels 223 .

[0062] Specifically, the first driving wheel 221 is mounted on one end of the fixed frame 211, and a plurality of guide wheels 223 are provided on one side of the fixed frame 211 away from the lifting frame 212. In this way, the crawler 23 can be better supported and the crawler 23 can be easily moved normally.

[0063] Specifically, the second driving wheel 222 is mounted on the extension section 2132, and the extension section 2132 is further provided with at least two guide wheels 223. In this way, it is convenient to support the crawler belt 23 corresponding to the extension section 2132, and it is also convenient for the crawler belt 23 to walk normally.

[0064] Specifically, a plurality of guide wheels 223 are provided on a side of the lifting frame 212 away from the fixed frame 211 , so as to facilitate support for the crawler track 23 corresponding to the lifting frame 212 and facilitate normal movement of the crawler track 23 .

[0065] In this embodiment, the plurality of rolling portions 22 include a second drive wheel 222, at least two first guide wheels, and at least two second guide wheels. The at least two first guide wheels are disposed on a side of the fixed frame 211 away from the lifting frame 212, and the at least two first guide wheels are spaced apart along a predetermined direction. The second drive wheel 222 and the at least two second guide wheels are both mounted on the extension section 2132, with the at least two second guide wheels positioned above the second drive wheel 222. The at least two second guide wheels are spaced apart along the periphery of the second drive wheel 222, and the top of one of the at least two second guide wheels is flush with the top of each first guide wheel. This structural arrangement ensures that the top of the track 23 is aligned as much as possible, reduces the likelihood of the track 23 becoming irregular, and facilitates normal movement of the track 23.

[0066] In this embodiment, the plurality of rolling portions 22 further include a first drive wheel 221 and at least two third guide wheels. The first drive wheel 221 is mounted on one end of the fixed frame 211, and the at least two third guide wheels are disposed on a side of the lifting frame 212 away from the fixed frame 211. The at least two third guide wheels are spaced apart along a predetermined direction. This structural arrangement facilitates smooth guidance and tensioning of the ends of the crawler tracks 23 by the third guide wheels, facilitating normal movement of the crawler tracks 23.

[0067] Specifically, the top of the first drive wheel 221 is flush with the top of each first guide wheel. This structural arrangement can ensure that the top of the track 23 is as flush as possible, reduce the probability of the track 23 being deformed, and thus facilitate the normal running of the track 23 and prevent the track 23 from falling off during deformation and tightening.

[0068] Specifically, the lifting frame 212 has an initial position in contact with the fixed frame 211. When the lifting frame 212 is in the initial position, the bottom end of the second drive wheel 222 is flush with the bottom end of each third guide wheel. This ensures that the bottom of the crawler track 23 is as flush as possible when the lifting frame 212 is in the initial position, reducing the possibility of the crawler track 23 being deformed and facilitating normal movement of the crawler track 23.

[0069] In this embodiment, the fixed frame 211 extends along a predetermined direction. The bolter miner further includes a lifting hydraulic cylinder and a plurality of lifting columns 40. The plurality of lifting columns 40 are spaced apart on the fixed frame 211 along the predetermined direction. One end of each lifting column 40 is connected to the lifting frame 212, and the other end of each lifting column 40 is connected to the fixed frame 211. Each lifting column 40 is height-adjustably arranged between the lifting frame 212 and the fixed frame 211. Each of the plurality of lifting columns 40 is connected to the lifting hydraulic cylinder. This facilitates smooth elevation of the lifting frame 212 relative to the fixed frame 211, thereby adjusting the relative position between the lifting frame 212 and the fixed frame 211 and facilitating adjustment of the chassis height of the machine body 10, thereby preventing the chassis from being scratched and damaged due to the chassis height being too low.

[0070] Specifically, when the anchor miner provided by this embodiment is used, the anchor miner (also known as the anchor miner) is moving in a tunnel, and there is a raised obstacle on the tunnel surface that prevents it from passing through in a normal posture. At this time, the lifting hydraulic cylinder is activated to extend the output shaft of the lifting hydraulic cylinder, thereby moving the lifting frame 212 away from the fixed frame 211, and the lifting column 40 moves downward from the slide slot, thereby raising the chassis height of the machine body 10. At the same time, the tensioning hydraulic cylinder (corresponding to the drive structure 30) is activated to shorten its output shaft, thereby moving the tensioning frame 213 toward the side of the machine head, retracting the drive wheel so that the crawler 23 can be tightened and prevented from collapsing. Then the drive wheel is activated to drive the crawler 23 to rotate. Due to the raised chassis of the machine body 10, the anchor miner can smoothly pass through the obstacle that was originally insurmountable, thereby improving the passability of the anchor miner, improving the single-entry level of the anchor miner, and reducing labor intensity.

[0071] Specifically, the anchor miner also includes an anchor bolter 60. When the anchor miner stops moving, the anchor bolter 60 performs anchor bolting operations, and the cutting arm 50 can cut the coal seam or rock in front. The cut coal or gangue is collected by the collecting shovel 70 and transported to the rear via the transportation mechanism 80. The above are all functions possessed by a conventional anchor miner, and its structure will not be repeated here.

[0072] From the above description, it can be seen that the above-described embodiments of the present invention achieve the following technical effects: By raising and lowering the lifting frame, the tensioning frame moves in a preset direction, adjusting the height of the machine body, thereby adjusting the height and position of the chassis, and ensuring that the crawler tracks are always in a tensioned state, effectively improving the adaptability and stability of the anchor miner under various operating conditions. Furthermore, the provision of a drive structure enables precise control of the tensioning frame, further enhancing the operating performance and efficiency of the anchor miner. This design not only simplifies the structure of the anchor miner and reduces maintenance costs, but also improves its operating efficiency and stability, offering significant benefits for excavation operations in complex working conditions such as coal mines and tunnels. In such complex working conditions, the anchor miner with this design can better adapt to the undulating ground conditions, automatically adjusting the tension of the crawler tracks, effectively improving operating stability and efficiency, and reducing crawler wear and the risk of derailment. The precise control of the drive structure makes the anchor miner more flexible and accurate in operation, improves operational continuity and safety, and reduces the overall cost of coal mine roadway excavation and tunnel construction, making it an ideal choice for navigating complex underground engineering environments. This design enables the bolter miner to perform excavation operations more stably and efficiently when dealing with complex geological conditions in coal mine tunnels, such as mud, rock, and coal seams. This reduces machine failures and maintenance time, and improves the safety and economic benefits of operations.
